To al!) whom z may concern.'

Beit known that we, HENRY P. DENNIS,AL BERTUs D. POTTER, and JOHN H. ELLIS, citizens of the United States, residing at Peoria,

in the county of Peoria and State of Illinois,

have invented certain new and useful Improvements in VVashing-"vlachines, and we do hereby declare that the following is a full, clear, and exact description of the invention,

1o which will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in washing-machines, and has for its object to provide a machine that will wash clothing of light weight and delicate texture or heavy and bulky clothes and bed-coverin gs with equal facility without harm to either.

A further object is to simplify the construction of such device, and make a light-ruuzo ning machine and one that will require very little labor in its operation.

In the accompanying drawings, Figure lis a front elevation of the machine, showing the feti. Fig. 2 is also z. of Fig. 1,showj in of cam.` A

e mac ine and tub. Fig.'

a friction disk orV button secured to a vertical shaft which carries a 3o dasher. Fig. 5 is a perspective view of a portion of a dasher. Fig. 6 is aplan view of the dasher, shown in full. Fig. 7 is a perspective View of a bearing for guiding the shaft or rod which carries the dasher.

3 5 In the figures, in which letters of reference correspond with those of the following specification, A represents a support or standard on a removable lid of a tub A. Said support carries a bearing Bat its upper end and one 4o near its base, which together support a vertically-shifting rod or shaft C, having at its upper extremity a handpiece or knob D, which may be Weighted to assist in the operation of the machine, if desired. The lower end of the rod is provided with a dasher, (shown in Figs. 5 and 6,) which consists of a central casting D', into which said rod is inserted and secured. A series of parallel slats E are attached to said casting by means of pins or riv- 5c ets F, as shown in Figs. l and 5. The ends of said slats are spaced apart and held by means of fillers G, and bolts H, running through the entire bunch, prevent warping of such slats if made of wood. We have shown the casting as provided with grooves 5 5 into which the slats are set, as will be understood by a study of Fig. 5.

An arm or projection-A2 on the standard A carries a horizontal shaft J, having at its rear end a crank I. To the forward end of said 6o shaftis attached au S-cam' J' of substantially the form shown, whose faces K bear upward against a disk orbutton L, secured to the shaft C. Said disk has a leather or rubber washer M beneath it, as in Fig. 4, and above it at N is a rubber washer which lessens the impact against the bearing B at the top of the standard A, likely to occur when in the act of raising. However, this is not necessary and said washer need not be used. The office of the 7o washer M is to create greater friction between the cam J and disk than would otherwise eX- ist were the bare metal used. The resulting friction' serves to turn the shaft O-in its bearings as the face of the cam slides beneath the said disk, thereby revolving the dasher, so

that it will fall in various positions, and thus reach all portions of the clothes being Washed. The curved` faces of the cam are not true arcs, but rather portions of ellipses, so that a 8o greater surface is in Contact with the disk L,

and thus friction sufficient to turn the dasher is assured. In theirlowest position the dasher and shaft C occupy the positiony about as shown in Fig. 1 in brokenlines, or Where the. 85

knee of the cam will pass beneath the diskL and raise it as the cam revolves. When raised to its highest point, the dasher drops by gravity by reason of the cam having passed from beneath the disk. A continued revolution of 9o the crank brings the opposite portion of the cam beneath the disk, and so on. In Fig. 2 We have illustrated only one-half of the cam and may so use it, as we do not confine ourselves to any particular construction. We prefer to wash clothing by means of a pounding and squeezing process, and on this line We have constructed our form of washing-machine and adapted it to this Work in the most simple manner. ticular form of dasher, nor do we wish to use any stated form. .Neither do we desire to con- We do not claim any par-v :loo

fine ourselves to the exact construction shown as to the entire apparatus.

Evidently the friction-washer M may be omitted and we simply roughen the metal contact-surfaces to accomplish the desired end. The utility of our machine is more than ever evident when it is known that the machine can be transported from tub to tub instead of having to move the clothes in doing the washlng.

When the clothes are in the tub, the disk L is at such a height that the heel of the cam will pass beneath it and raise it on its face, as described. As the dasher rises it will naturally turn in its bearings by the friction of the cam on the disk, and when liberated the dasher, by reason of acquired momentum, will descend upon the clothes with a rotary motion, and thus better accomplish the separation of the dirt by working into and under the clothes. IVe are aware that machines have been employed wherein cams or eccentrics have been used to raise the dasher, and also that the shaft for carrying and driving the cam of the machine was carried at a point remote from the dashershaft; but we use and Claim a different construction from those. As stated above, the dasher descends upon the clothes with a.rotary motion, which serves to better accomplish separation of the dirt than by a vertical drop. It very often happens that in dropping in the manner described some of the clothes fall over upon the dasher, and are thus raised from the water and disarranged,

besides making the device hard to manipulate. To obviate this difiiculty, the hollow portion of the face of the cam J between 4the shaft .I and the knee or heel of the arm is designed to come beneath the disk L when the desired amount of clothes are in the tub to raise the dasher to the proper height to permit the parts to meet, as described. It will be readily understood that as the upper arm J revolves toward the left, as shown in Fig. l, the shaft C and its dasher will revolve toward the right; but when the hollow oE the arm is contacting with and raising the disk L the motion of the said shaft is reversed by the reverse curve until the knee reaches the disk. Then the motion is again toward the right. The reverse movement is sufficient to draw the dasher out from its position and make it traverse the same path at which it entered, and will thus draw it out from under the clothes that may fall upon it.

In use the knob D may be heavily weighted, as before intimated, so that it, combined with the weight of the dasher and shaft, will aid in pounding the clothes. Instead of the Weight the operator may place his hand upon the knob and apply pressure to accomplish the same end, as is evident.

Having thus described our invention, what we claim as new, and desire to secure by Letters (Patent, is

The combination with the tub A', of the standard A, the lid on which the saidstandard is mounted, the vertical shaft C adapted for vertical movement, bearings B for guiding the same, the dasher on the lower end of said shaft C, the disk L on said vertical shaft, the projection A2 on the standard A, the horizontal shaft .I and its crank mounted on said projection, the cams J secured to said horizontal shaft and adapted to engage the said disk L on the .shaft C, each of said cams consisting of an arm extending substantially straight away from the shaft and each also being formed with a knee extending out-ward and away from said straight portion at an obtuse angle thereto into the path ot' the cams and in the direction of revolution thereof and also having a curved extremity K substan tially at right angles to said knee and extending back into the path traversed by said cams in such manner that when the crank is turned said knee first meets the disk L and raises and turns the dasher in one direction and when the outer curved extremity meets said disk the dasher is turned in the opposite direction as set forth and for the purposes described.

In testimony whereof We affix our signatures in presence of witnesses.
